Short/vertical takeoff and landing (S/VTOL) aircraft combine the advantages of helicopters and conventional fighter jets. The aircraft realizes S/VTOL through the lift generated by the propulsion system. Therefore, the propulsion system for S/VTOL aircraft has always been the focus of research in various developed aviation countries (Anderson 1983; Ransone 2002). The three-bearing swivel nozzle has emerged as a key research focus for S/VTOL thrust vectoring nozzles due to its structural simplicity, lightweight design, and high degree of freedom characteristics (Suo et al. 2014). Comprising three mutually rotatable cylindrical sections, the nozzle achieves thrust vectoring by adjusting the rotational angles and combinations of these sections (Liu et al. 2015).

摘要

Short/vertical takeoff and landing (S/VTOL) aircraft combine the advantages of helicopters and conventional fighter jets. The aircraft realizes S/VTOL through the lift generated by the propulsion system. Therefore, the propulsion system for S/VTOL aircraft has always been the focus of research in various developed aviation countries (Anderson 1983; Ransone 2002). The three-bearing swivel nozzle has emerged as a key research focus for S/VTOL thrust vectoring nozzles due to its structural simplicity, lightweight design, and high degree of freedom characteristics (Suo et al. 2014). Comprising three mutually rotatable cylindrical sections, the nozzle achieves thrust vectoring by adjusting the rotational angles and combinations of these sections (Liu et al. 2015).
